AudioControl EPICENTER Micro PRO Bass Restoration Processor & Line Output Converter
Adding a subwoofer amplifier to a factory system can create two separate problems: the radio may roll bass off as volume increases, and its speaker-level output may not be a clean match for an aftermarket amplifier. The EPICENTER Micro PRO is designed to handle both sides of that job in one compact processor.
It combines AudioControl bass restoration with a full line-output-converter input stage, selectable speaker-load settings, multiple turn-on methods and a built-in line driver. Compared with the larger EPICENTER PRO, the Micro PRO is the better fit when the signal is coming directly from a factory speaker circuit or when installation space is tighter.

What’s in the Box
EPICENTER Micro PRO processor, ACR-4 dual-knob remote, remote cable, speaker and power connectors, and user manual.
Good fit: factory-radio systems that need a proper speaker-level interface plus bass restoration, or compact installs where the 3-inch-deep chassis is easier to package. Already have a clean RCA/preamp-level signal and do not need OEM speaker-level integration? The EPICENTER PRO is the simpler choice.
Where this fits in the build
This is a system-control or DSP component. The correct choice depends on the signal path, channel count, routing, retained features and the rest of the amplifier and speaker plan.
